The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.
It should be noted that in the embodiments of the present application, the term "comprising" is used to indicate the presence of the features stated hereinafter, but does not exclude the addition of further features.
At present, the operation effect is presented on the three-dimensional control of the interface by converting the operation of the keyboard and the mouse at the PC end. However, the following two problems may occur:
firstly, the three-dimensional interaction process of the PC terminal mainly comprises a clicking type and a dragging type, and the problems that the operation is not responded or the response is repeated frequently and the like can occur due to the influence of the visual angle position in the specific using process. For high-risk simulation fields or scenarios where operations are to be completed in a short time, such problems may lead to serious consequences.
Secondly, the three-dimensional interaction at the PC end is generally completed only through a mouse and a keyboard, and due to the limitation of hardware conditions of the mouse and the keyboard, the current three-dimensional interaction process only can show a click or drag effect, and cannot simulate damping feeling and click feeling in a real scene.
Based on the above problems, the embodiments of the present application provide a three-dimensional model operation control method, which obtains target positions mapped on an operator and a three-dimensional control by using two mapping models after a user operates a mouse, and correspondingly moves an icon to the target positions, so that the obtained target positions are more accurate, the problem of non-response or multiple responses can be avoided, and damping feeling and click-and-pause feeling in a real scene can be simulated.
The method and the device for mapping the operation of the terminal device to the target positions on the operator and the operation control can be applied to a three-dimensional simulation scene, in which a three-dimensional model is displayed in a display screen of the terminal device, the three-dimensional model comprises at least one operation control, a user can use a mouse to control the operation control, and when the user controls, the terminal device maps the operation of the user to the target positions on the operator and the operation control based on the method of the embodiment of the application and correspondingly moves the icon to the target positions.
Fig. 1 is a schematic flowchart of a three-dimensional model operation control method provided in an embodiment of the present application, where an execution subject of the method is a terminal device including a mouse, for example, a PC. As shown in fig. 1, the method includes:
s101, when a user uses a mouse of the terminal device to operate a target control, displaying an operator on an interface of the terminal device, wherein the operator comprises the following display elements: an operating rod and a mouse indicating ball.
Before executing the step, a three-dimensional model to be operated is displayed on an interface of the terminal device, for example, the three-dimensional model may be a three-dimensional model of a train console, and the like.
The three-dimensional model comprises at least one target control to be operated and capable of adjusting gears, and a user can adjust the gears of the target controls by dragging a mouse.
It should be noted that the operation control in the three-dimensional model may include various types, such as a knob type, a button type, and the like. Regardless of the type of control, the control may be a target control for the adjustable gear as described herein, as long as the control is adjustable. For example, a certain control is a press type control, which is opened after being pressed for the first time, closed after being pressed for the second time, and so on, then the press type control may be used as a target control with adjustable gear according to the present application, and display processing is performed according to the method of the present application.
When the user operates the target control by using the mouse, the terminal equipment can display the operator on the interface. In the embodiment of the application, the operator is an interface element displayed by the terminal device, is independent of the three-dimensional model, and is used for timely positioning a certain target control when a user operates the target control and timely presenting the effect of the user on operating the target control. Therefore, in the application, after the user operates the target control, the operation effect can be presented on the operator and the three-dimensional model of the target control at the same time.
Fig. 2 is an exemplary diagram of a three-dimensional model and an interface of an operator, as shown in fig. 2, the three-dimensional model displayed by the terminal device includes a target control a with adjustable gears, and when a user operates the target control a through a mouse, the terminal device may display the operator in a semi-transparent manner above the target control a.
Alternatively, the operator displayed on the terminal device may include a joystick and a mouse pointer. The operating rod can be used for representing the range of the target control operation, and the position of the mouse indicating ball on the operating rod represents the effect of the target control operation of the user. Illustratively, when the user does not drag the mouse for the target control, the mouse indicating ball is located at the starting end of the operating rod, and after the user drags the mouse, the mouse indicating ball is displayed at the corresponding position of the operating rod according to the distance dragged by the user.
S102, obtaining operation data when a user operates a target control by using a mouse, wherein the operation data comprises: the drag direction and the drag distance.
Optionally, the terminal device may determine whether the user starts to drag the mouse by monitoring a click event, a movement event, and a release event of the mouse, and calculate a drag direction and a drag distance when the user drags the mouse based on a position coordinate of a mouse pointer on a display screen of the terminal device in a process that the user drags the mouse.
And S103, performing first mapping processing on the operation data based on a first mapping model to obtain a target position of the operation data mapped on the operating rod, and displaying the mouse indicating ball at the target position.
The first mapping model is used for mapping the operation of the user to the operator so as to present the effect of the user after the operation on the operator.
By using the first mapping model, the terminal device can calculate a target position where the mouse indication ball should be located on the operation rod after the user moves the mouse in the dragging direction for the target control by the dragging distance, and the terminal device moves the mouse indication ball to the target position, namely, the mouse indication ball is displayed on the target position.
Alternatively, in the embodiment of the present application, the position of the element may be represented by coordinates of the element on the display screen. Accordingly, the mouse indicates the target position of the ball on the joystick, and may refer to coordinates on the display screen that are within the range of the joystick.
And S104, performing second mapping processing on the operation data based on a second mapping model to obtain a target gear of the operation data mapped on the target control, and switching the gear of the target control in the three-dimensional model to the target gear.
The second mapping model is used for mapping the user operation to the target control so as to present the effect of the user after the user operation on the target control.
By using the second mapping model, the terminal device can calculate whether the gear of the target control needs to be switched to other gears except the current gear after the user moves the mouse by the dragging distance according to the dragging direction for the target control, and if so, the gear of the target control is switched to other corresponding gears.
It should be noted that, in the specific implementation process, the execution sequence of the steps S103 and S104 is not sequential.
In this embodiment, when the user operates the target control of the three-dimensional model using the mouse, the terminal device displays the operator on the interface, and the terminal device further obtains the target position of the user operation mapped on the operating rod of the operator using the first mapping model, obtains the target gear of the user operation mapped on the target control using the second mapping model, and presents the mapped effect on the operator and the target control. Because the terminal equipment uses the two mapping models to respectively map the user operation to the operator and the target control, more accurate mapping can be carried out according to the characteristics of the operator and the target control, the accuracy of the obtained target position is higher, the problem of no response or multiple responses can be avoided, and the damping sense and the pause sense in a real scene can be simulated.
The following describes the process of the terminal device performing the mapping process based on the first mapping model and the second mapping model, respectively.
Fig. 3 is a schematic flowchart of a terminal device performing mapping processing based on a first mapping model, and as shown in fig. 3, an optional manner of the step S103 includes:
and S301, acquiring the gear number of the target control and the distance between adjacent gears.
Optionally, the number of the gears of the target control is an inherent parameter of the three-dimensional model, and the number of the gears can be obtained by reading parameter information of the three-dimensional model. The distance between adjacent gears can be obtained by calculating the distance between the coordinates of the center points of the adjacent gears.
S302, inputting the gear number, the distance between the adjacent gears and the operation data into the first mapping model to obtain a target position of the operation data mapped on the operation rod, and displaying the mouse indicating ball at the target position.
Optionally, the number of gears, the distance between adjacent gears, and the operation data are used as input parameters of a first mapping model, and the first mapping model performs a first mapping process based on the input parameters, so that a target position of the operation data mapped on the operation lever can be obtained.
Optionally, the first mapping model may be a machine learning model obtained by training in advance using a training sample, or may also be a mapping model composed of several calculation formulas.
Regardless of the form of the first mapping model, the first mapping model may perform the mapping as follows.
As an alternative embodiment, the first mapping model may be configured to perform length averaging on the operation levers according to the number of the gear positions to obtain a plurality of candidate positions that are the same as the number of the gear positions, and select one candidate position from the plurality of candidate positions as the target position according to the distance between the adjacent gear positions and the operation data.
In one example, assuming that the number of shift positions is 2, after the length of the operating lever is averaged, two candidate positions are obtained, one candidate position is a start position of the operating lever, and the other candidate position is an end position of the operating lever.
In another example, assuming that the number of shift positions is 3, after the length of the operating lever is averaged, three candidate positions are obtained, where a first candidate position is a start position of the operating lever, a second candidate position is a position of a half length of the operating lever, and a third candidate position is an end position of the operating lever.
After the processing, each gear of the target control can respectively correspond to a to-be-selected position on the operating rod. After the user drags the mouse, the mouse indicates that the ball may only be located in one of these candidate positions.
Optionally, the terminal device may determine, based on the dragging distance and the distance between adjacent gears, whether the distance dragged by the user has satisfied the distance to another gear, and if yes, determine, by combining with the dragging direction, a to-be-selected position corresponding to another gear on the operation rod before or after the mouse indication ball is moved to the current position. If not, the terminal device can keep the position of the mouse pointing ball unchanged.
Exemplarily, assuming that the number of gears is 3, the terminal device determines, based on the dragging distance and the adjacent gear distance, that the dragging distance of the user meets the distance to the adjacent gear of the current gear, and then, the terminal device determines, according to the dragging direction, that the user drags the mouse in the direction of the next gear of the current gear, so that the terminal device can use the to-be-selected position corresponding to the next gear of the current gear on the operating rod as the target position, and move the mouse indication ball to the target position.
Fig. 4 is a schematic flowchart of a process of performing mapping processing by a terminal device based on a second mapping model, and as shown in fig. 4, an optional manner of the step S104 includes:
and S401, acquiring the distance between adjacent gears of the target control.
The manner of obtaining the distance between adjacent gears of the target control in this step is the same as that in step S301, and reference may be made to the description of step S301, which is not described herein again.
S402, inputting the distance between the adjacent gears and the operation data into a second mapping model to obtain a target gear of the operation data mapped on the target control, and switching the gear of the target control in the three-dimensional model to the target gear.
Optionally, the distance between the adjacent gears and the operation data are used as input parameters of a second mapping model, and the second mapping model performs second mapping processing based on the input parameters, so that a target position of the operation data mapped on the operation rod can be obtained.
Optionally, the second mapping model may be a machine learning model obtained by training in advance using training samples, or may also be a mapping model composed of several calculation formulas.
Regardless of which form the second mapping model takes, the second mapping model may accomplish the mapping as follows.
As an optional implementation manner, the second mapping model may be configured to determine whether to perform gear shifting according to the operation data and the distance between adjacent gears, and when determining to perform gear shifting, use a previous gear or a next gear of a current gear of the target control as the target gear.
Alternatively, the terminal device may perform linear or nonlinear processing based on the operation data and the distance between adjacent gears. For example, when the dragging distance is greater than or equal to half of the distance between adjacent gears, the terminal device may determine to perform gear shifting, and determine, based on the dragging direction, that the target gear to be shifted is the previous gear or the next gear of the current gear.
It is worth noting that when the user drags the mouse, the dragging may be continued for a long distance, and the total distance of dragging may be greater than the distance between adjacent gears of the target control. For the situation, the terminal device can monitor the dragging distance of the mouse in real time, once the distance of the mouse can be switched to the previous gear or the next gear is reached, gear switching and display can be completed in the above mode, and then the position after gear switching and display are taken as the new current gear, judgment and processing are continued based on the above mode, and by analogy, the specific execution process is not repeated.
In this embodiment, the second mapping model determines whether to perform shift switching based on the operation data and the distance between adjacent shifts, and does not perform shift switching when the operation data does not satisfy a specific condition, thereby better simulating a damping feeling and a click feeling of an operation.
The following describes a processing procedure when the terminal device displays the above-described operator on the interface.
As mentioned above, the operator may include a joystick and a mouse pointer, and as an alternative, the operator may further include: selecting a middle frame and a prompt frame. An example of a checkbox and prompt box interface may be found in FIG. 2, previously described. A checkbox may be displayed in a semi-transparent manner over the target control to indicate that the target control is currently being operated by the user. The prompt box is used for displaying the information of the selected target control. For example, the information of the target control displayed by the prompt box may include: name, state value, and operation mode of the target control.
Fig. 5 is a schematic flowchart of a process for displaying an operator on a terminal device, and as shown in fig. 5, an alternative way for displaying the operator on the interface of the terminal device in step S101 includes:
and S501, determining the display position of the selected middle frame according to the position of the target control on the interface.
Optionally, the position of the target control on the interface may refer to a two-dimensional coordinate of a center point of the target control on the interface. The terminal device may first obtain a three-dimensional position coordinate of the center point of the target control in the three-dimensional model, and map the three-dimensional position coordinate to the two-dimensional interface, so as to obtain a two-dimensional coordinate of the center point of the target control on the interface.
After obtaining the two-dimensional coordinate of the center point of the target control on the interface, the two-dimensional coordinate may be used as the display position of the selected middle frame.

Specifically, in this step, the rotation angle of the operator may be determined according to the positions of the two ends of the target control and the initial position of the operation rod. The initial position of the operating rod is the position of the operating rod at the moment before the user operates the target control, and the initial position of the operating rod can be represented by the positions of two end points of the operating rod, and a ray can be obtained through the positions of the two end points.
It should be noted that if the current target control is the first target control to be operated, that is, the operator is not displayed on the interface before the current target control is operated, the initial position of the joystick may be a default position parallel to the bottom end of the screen. The positions of the two ends of the target control can represent the positions of two end points of the target control, and the other ray can be obtained through the positions of the two end points. Furthermore, the angle formed between the two rays can be used as the angle difference between the operating rod and the target control, and the angle difference can be used as the rotation angle of the operator.
And S503, rotating the operator according to the rotation angle, displaying the center selection frame on the display position of the center selection frame according to the rotated angle, and displaying the operation rod, the mouse indication ball and the prompt box according to the preset position relation between the center selection frame and the operation rod, the mouse indication ball and the prompt box.
Optionally, the center selection box, the joystick, the mouse pointer and the prompt box in the operator are used as the constituent elements of the operator, and the position relationship in the operator is preset and fixed. Therefore, the operating rod, the mouse pointer and the prompt box can be displayed simultaneously according to the fixed position relation while the selection box is displayed at the determined display position according to the rotation angle of the operator, so that the display of the operator above the target control is realized.
Optionally, when the prompt box is displayed, the name, the state, the operation mode, and the like of the currently operated target control may be displayed in the prompt box. The state of the target control can be the current gear of the target control, and the state can be updated in real time along with the operation change of a user. The operation mode of the target control may be, for example: rotate, click, etc.
As an alternative implementation, after the terminal device displays the operator on the interface, the system mouse icon displayed on the interface of the terminal device may be hidden.
After the processing of the foregoing embodiment, when the user operates the target control, the terminal device displays the operator on the interface, and adjusts the position of the mouse indication ball on the operation rod according to the operation data of the user on the system mouse, the user can know the state change of the target control according to the position change of the mouse indication ball, and the position of the system mouse icon has a small effect on the user in this scene, so that the terminal device can hide the system mouse icon, thereby avoiding interference with the user, and improving the experience of the user.
